In 1235 Henry the Third upheld the Canons’ Court against the City.

The erection of St. Leonard’s Parish Church on the confines of the Precinct in 1236 points to a restriction of St. Martin’s Church to the College or sanctuary. But there are other instances, e.g. that of St. Catherine Cree, in which a parish church was, for convenience, built outside the Monastic Precinct.

The buildings of St. Martin’s were improved and rebuilt by its Dean, William de Wykeham, about 1367.

Pope Innocent the Third exempted the Royal Chapels from Excommunication or Interdict.

THE SANCTUARY OF ST. MARTIN’S-LE-GRAND
From Strype’s Stow, 1754 edition.

Edward the First forbade Cardinals sent from Rome to receive procuration from St. Martin’s.

In 14 Edw. II. the College, under a Quo Warranto heard at the Tower, relinquished any claim to receive toll within the City.

By Rich. II. St. Martin’s was exempted from tenths, fifteenths, tallages, aids, and all contributions or quotas by the King.
